Both, app-text/qpdfview-0.4.13 and www-client/qupzilla-1.8.6 when built with qt5 (dev-qt/qtcore-5.4.1) crash immediately when the application tries to print. This occurs before any pop-up menu for printing appears. Here is a backtrace for qupzilla : Program received signal SIGSEGV, Segmentation fault. 0x0000000000000000 in ??
